Errors after Updating firmware in Modular Gateway

I have updated the firmware of the Modular gateway router to 1.7.17_golden.swu

From then, i am not able to detect my edge node NFC tag. i am able to turn on NFC through the application in the gateway . And i was able to do all these before upgrading. I have also upgraded the firmware on edge node. Can anyone help me ??

You can confirm the NFC commissioning status using the LED2 on the gateway board. If the LED2 blinks fast for 10 times, it means that the commissioning is successful for the end device. If the LED2 blinks slowly for 5 times, it means that the commissioning is failed for the end device. Please check the MGOOBDSUG.docx document for more details on the LED2 states.

If the commissioning is failed, you can check the debug logs for the gateway. The debug logs are stored in "/var/log/VMGAppFull" file on the modular gateway.

You can also check that the NFC tag has valid data using NFC Tools Android application from NFC enabled smartphone.

The possible reason which can cause the NFC commissioning fail are below.

The gateway does not have an active internet connection. You can confirm that the gateway is connected to the cloud using state of LED1 (should be Green).

The NFC tag does not have the valid commissioning data. To confirm this you can check the NFC tag content from the NFC enabled smartphone as mentioned in the previous comment.

The end device with the EUI address mentioned in the NFC tag is failed to validate with the cloud. This might happen if you are using Thread end node and have updated the end node firmware to IDEx 1.2.1. As the KW41Z binary file is based on an updated Thread stack (starting from IDEx 1.2.1), its MAC address might change when updating the device from an old firmware (built with IDEx 1.2.0.1 or before) to a newer firmware (built with IDEx 1.2.1 or after). Please follow the MGOOBDSUG.docx document to get the EUI address from end node and commission again.

You may also need to update the KW41Z module on the gateway because Backward/Forward compatibility is not supported in Gateway and Thread Ende device between IDEX 1.2.1 and earlier IDEX version. Please check RELEASE_NOTES.txt from IDEx 1.2.1 release package for more details.
